Reduce the function pointer mess of the m68knommu timer code by calling
directly to the local hardware's timer setup, and expose the local
common timer interrupt handler to the lower level hardware timer.
Ultimately this will save definitions of all these functions across all
the platform code to setup the function pointers (which for any given
m68knommu CPU family member can be only one set of hardware timer
functions).

A new style serial driver for the Freescale ColdFire UART to replace
the old style one currently in the tree (drivers/serial/mcfserial.c).
Currently this UART is only found in the ColdFire CPU family of parts
(thus I prefixed this patch [M68KNOMMU]).
This has been around for a long while now, tested on all available
platforms.

Up to now m68knommu has been using the asm-m68k/module.h instead of
defining its own. There are recent changes there that we don't need
(fixups specifically). We don't need much support here so it makes
sense to have an m68knommu specific one now.

ztxdone is jumped to even if tty is NULL and tty_wakeup placed after
this label doesn't expect NULLed parameter, so this will cause an oops
in some situations (why they scheduled a wakeup there before remove
bottom half processing patch?).
wakeup only in the case when we have non-null tty struct.

Fix mprotect bug in recent commit 3ed75eb8f1
(setup vma->vm_page_prot by vm_get_page_prot()): the vma_wants_writenotify
case was setting the same prot as when not.
Nothing wrong with the use of protection_map[] in mmap_region(),
but use vm_get_page_prot() there too in the same ~VM_SHARED way.

ops_complete_biofill() runs outside of spin_lock(&sh->lock) and clears the
'pending' and 'ack' bits. Since the test_and_ack_op() macro only checks
against 'complete' it can get an inconsistent snapshot of pending work.
Move the clearing of these bits to handle_stripe5(), under the lock.

The mv643xx ethernet silicon block is also found in a couple of other
Marvell chips. As a first step towards splitting off the mv643xx_eth
bits from the rest of the mv643xx bits, this patch splits the mv643xx
ethernet platform device data struct in linux/mv643xx.h off into
linux/mv643xx_eth.h, and includes the latter from the former.

Implement at32_add_device_cf() which will add a platform_device for
the at32_cf driver (not merged yet). Separate out most of the
at32_add_device_ide() code and use it to implement
at32_add_device_cf() as well.
This changes the API in the following ways:
* The board code must initialize data->cs to the chipselect ID to
use before calling any of these functions.
* The board code must use GPIO_PIN_NONE to indicate unused CF pins.

Implement functions for adding platform devices for TWI, MCI, AC97C
and ABDAC. They may need to be modified to cope with platform data,
etc. when the corresponding drivers are ready to be merged, but such
changes are much less likely to conflict than adding support for a
whole new type of device.
